Description

Technical Field

[0001] The utility model relates to the technical field of jammers, in particular to a rotary omnidirectional recording jammer. Background Art

[0002] Ultrasonic recording shielding technology is one of the main methods to prevent illegal recording. It uses the characteristics of ultrasound to interfere with the normal operation of recording equipment. Traditional ultrasonic recording shielding equipment usually consists of fixed ultrasonic vibrators, control circuits and power supply systems. It can be widely used in conference rooms, offices, private homes and other places that require confidentiality to prevent unauthorized recording. The high-frequency sound waves emitted by ultrasonic vibrators can interfere with the pickup system of recording equipment, making the recorded audio content unclear or completely unrecognizable.

[0003] However, due to the strong directivity of ultrasonic wave propagation, the traditional ultrasonic recording shielding equipment can only provide effective shielding effect within a limited angle range with fixed ultrasonic vibrators. This means that there may be "dead corners" around the equipment that are not fully covered, reducing the overall shielding effect. In order to achieve all-round shielding, traditional equipment often needs to install multiple ultrasonic vibrators, which increases the complexity and volume of the equipment and significantly increases the production and use costs. The fixed design also limits the flexibility of the equipment, making it difficult to adapt to different usage environments and changes in demand. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a rotating omnidirectional recording shield, comprising a bottom plate, the top of which is installed with: a rotating mechanism, which is arranged in the middle part of the bottom end of the bottom plate, and the top end extends to the top of the bottom plate; columns, the bottom ends of several columns are respectively installed on the edge of the bottom plate at equal distances by bolts; a top plate, which is connected to the top ends of several columns by bolts and corresponds to the bottom plate; a shielding mechanism, which is installed on the driving end of the rotating mechanism; a protective cover, the top and bottom ends of the protective cover are respectively abutted between the top plate and the bottom plate; a control module, which is respectively connected to the rotating mechanism and the shielding mechanism.

[0011] Compared with the prior art, the beneficial effect of the utility model is that the rotary omnidirectional recording shielding device uses a rotary motor to drive the ultrasonic vibrator to rotate 360 ​​degrees, thereby achieving an all-round recording shielding effect without dead angles.

It overcomes the dead angle problem existing in traditional fixed shielding devices and significantly improves the shielding effect. It improves the effect and coverage of recording shielding, and also enhances the stability, safety and ease of use of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figures 1 to 3 The utility model provides a technical solution: a rotary omnidirectional recording jammer, comprising a bottom plate 1, the top of which is installed with: a rotating mechanism 2, a column 3, a top plate 4, a shielding mechanism 5, a protective cover 6 and a control module, the rotating mechanism 2 is arranged in the middle part of the bottom end of the bottom plate 1, and the top end extends to the top of the bottom plate 1; the bottom ends of a plurality of columns 3 are respectively installed at the edge of the bottom plate 1 at equal distances by bolts; the top plate 4 is connected to the top ends of a plurality of columns 3 by bolts, and corresponds to the bottom plate 1; the shielding mechanism 5 is installed on the driving end of the rotating mechanism 2; the top and bottom ends of the protective cover 6 are respectively abutted between the top plate 4 and the bottom plate 1; the control module is respectively connected to the rotating mechanism 2 and the shielding mechanism 5.

[0018] In the specific implementation process, it should be noted that when performing recording shielding, the control module is started, wherein the control module can be designed in the form of a main board, and a corresponding battery for powering the main board is also provided. The control module also includes a switch 10 and an indicator light 11. Pressing the switch 10 and starting the device controls the power supply received from the battery. And activate the rotating mechanism 2 to start it. The driving end of the rotating mechanism 2 drives the shielding mechanism 5 installed thereon to start rotating, and the ultrasonic vibrator 51 inside the shielding mechanism 5 rotates 360 degrees in all directions. At the same time, the control module also starts the shielding mechanism 5, and the shielding mechanism 5 spreads to the surroundings in a dead angle-free manner through rotation. When there is a recording device in the surrounding environment, it will interfere with the pickup membrane of the recording device, causing the recording content to become unrecognizable noise. During the whole process, the bottom plate 1 provides stable support for the device, a number of columns 3 and the top plate 4 form an overall frame structure, and the protective cover 6 wraps the entire device to play a protective role. This device ensures continuous and effective all-round recording shielding. By combining rotary shielding and electronic control, an efficient and comprehensive recording protection function is achieved.

[0019] In some examples, further, the rotating mechanism 2 includes: a rotating motor 21, a cylindrical plastic part 22 and a circuit board 23, the rotating motor 21 is fixedly installed in the middle part of the bottom end of the base plate 1, and the driving end extends above the base plate 1; the bottom end of the cylindrical plastic part 22 is fixedly set on the driving end of the rotating motor 21; the bottom end of the circuit board 23 is set at the top end of the cylindrical plastic part 22.

[0020] During the specific implementation process, it should be noted that when the device is started, the control module first sends a start signal to the rotating motor 21. The rotating motor 21 adopts a brushless motor, which drives the cylindrical plastic part to rotate at a speed of 500RPM. A circuit board 23 is installed on the top of the cylindrical plastic part 22, and the circuit board 23 also rotates 360 degrees. A shielding mechanism 5 is installed on the circuit board 23 to achieve all-round coverage through rotation. The cylindrical plastic part 22 plays a role of connection and insulation, ensuring that the rotational power of the motor can be stably transmitted to the circuit board 23, and also plays a certain role in shock absorption and noise reduction. The rotating mechanism 2 enables the shielding device to perform a continuous and stable 360-degree rotation, thereby achieving an all-round, no-dead-angle recording shielding effect.

[0021] In some examples, further, the shielding mechanism 5 includes: an ultrasonic vibrator 51 and a conductive slip ring 52, and a plurality of ultrasonic vibrators 51 are arrayed on both sides of the cylindrical plastic part 22; the conductive slip ring 52 is arranged in the middle part of the top of the top plate 4 and connected to the circuit board 23.

[0022] In the specific implementation process, it should be noted that when the device is started, the control module activates the shielding mechanism 5. The circuit board 23 starts to supply power to the ultrasonic vibrator 51 and transmit control signals. Multiple ultrasonic vibrators 51 are installed in an array on both sides of the cylindrical plastic part 22. As the rotating mechanism 2 operates, the ultrasonic vibrator 51 starts to rotate 360 ​​degrees. The ultrasonic vibrator 51 starts to emit high-frequency ultrasonic waves, and the frequency is usually more than 20kHz. The ultrasonic waves spread to the surrounding space in an all-round and dead-angle-free manner. During the rotation process, the conductive slip ring 52 located in the center of the top plate 4 maintains a continuous electrical connection with the circuit board 23 to ensure that the power supply and control signals can be transmitted to the ultrasonic vibrator 51 uninterruptedly during the rotation process. Even in the high-speed rotation state, the ultrasonic vibrator 51 can continue to work stably. The emitted ultrasonic waves will interfere with the recording equipment in the surrounding environment, causing its pickup membrane to vibrate irregularly, thereby converting any attempted recording into unrecognizable noise. The control module may adjust the frequency and intensity of the ultrasonic waves as needed to cope with different recording equipment and environmental conditions to achieve the best shielding effect. By using the rotating mechanism 2 in combination with a plurality of ultrasonic vibrators 51, the effect and coverage of recording shielding are greatly improved.

[0023] In some examples, further, a plurality of support plates 7 are installed in an array at the bottom end of the base plate 1, and an anti-skid pad 8 is provided in the middle of the plurality of support plates 7. The plurality of support plates 7 installed in an array at the bottom end of the base plate 1 provide additional stability and load-bearing capacity. The support plates 7 are evenly distributed under the base plate 1 to form a stable support network. An anti-skid pad 8 is provided in the middle of each support plate 7, and when the device is placed on a plane, the anti-skid pad 8 is in direct contact with the plane. The friction between the device and the ground is increased, effectively preventing the device from sliding due to vibration or external force during operation, and absorbing part of the vibration to reduce noise transmission. The anti-skid pad 8 can also protect the placement surface from being scratched. After the device is started, the rotating mechanism 2 and the shielding mechanism 5 start to work, which may generate certain vibrations and rotational forces. The combined structure of the support plate 7 and the anti-skid pad 8 can effectively disperse and absorb these forces to ensure that the device remains stable and does not tilt or move. The stability and safety of the device have been improved, and its adaptability on various surfaces has also been enhanced, allowing the device to reliably perform the recording masking function in different environments.

[0024] In some examples, further, the bottom end of the top plate 4 and the bottom end of the bottom plate 1 are provided with a plurality of limiting protrusions 9 for limiting the protective cover 6, the protective cover 6 is provided with a hollow structure, and the inner wall surface abuts against the plurality of limiting protrusions 9, and the diameters of the protective cover 6, the bottom plate 1 and the fixed plate are the same. The protective cover 6 adopts a hollow structure, which reduces the overall weight and is conducive to heat dissipation and sound wave propagation. The diameter of the protective cover 6 is completely consistent with that of the bottom plate 1 and the top plate 4, ensuring the coordination and aesthetics of the overall structure. During installation, the operator places the protective cover 6 between the bottom plate 1 and the top plate 4. The top end of the bottom plate 1 and the bottom end of the top plate 4 are provided with a plurality of limiting protrusions 9, and the limiting protrusions 9 correspond precisely to the inner wall surface of the protective cover 6. When the protective cover 6 is placed in place, its inner wall surface will abut closely against the limiting protrusions 9. Multi-point positioning and fixation are achieved to ensure that the protective cover 6 in the device can remain stable in both horizontal and vertical directions. The limiting protrusion 9 not only prevents the protective cover 6 from rotating or moving laterally, but also provides support in the vertical direction to prevent the protective cover 6 from moving up and down. The hollow design also allows the operator to observe the working status of the internal components without removing the protective cover 6. It not only ensures the firm installation of the protective cover 6, but also facilitates daily maintenance and inspection, while also taking into account the heat dissipation requirements and overall aesthetics of the equipment. During the long-term use of the equipment, this carefully designed protective cover 6 structure will continue to play a role, ensuring that the rotating omnidirectional recording jammer can safely, stably and efficiently perform its recording jamming function.
